Security policies are abstract descriptions of how a system should behave to be secure. They typically express what is obligatory, permitted, or forbidden in the system. When the s...
This paper shows that satisfiability for Propositional Dynamic Logic with Intersection is EXPSPACE-hard. The proof uses a reduction from the word problem for alternating, exponent...
The construction of an associative -product of traces from an earlier paper is revisited using projection representation of traces. Using projections instead of trace prefixes res...
